Hi.
Began to appear doubles topics with the same content.
/forum/forum21/topic1428/
/forum/forum16/topic1428/
The database entry with slug "topic1428" is only 1. And belongs forum, too, one "16"
How could appear I do not know.
Hi @vasiliy,
Please try to find and delete the "Invalid X frame" topic from Dashboard. The published topics and post you can find on Dashboard > Forums > Moderation > Published subtab.
But I have no topics and posts on moderation
Remove all topics, where the line will be specified "Invalid X frame". I need to look through all the topics and look for "Invalid X frame"? I understand correctly?
yes, @vasiliy, you need to find and remove the duplicated topic.
But there is no duplicated topic in admin panel. If I delete one duplicate topic, the other disappears too.
